Load Limit Switch on Hoist
The load limit switch can be installed onto a hoist at the rope's dead end or equalizer sheave. It can be designed for other installations with a power reel or remote control.
The load limit device is activated from the deflection of the rope when the hook lifts the load. This increases the tension of the rope, which activates the limit device. The device can be electrically connected with the hoist's switch for either up or down motion, depending on the motion to be controlled. As well, it can work as both an upper limit switch and load limit switch as a special order.
